- Series 1200 are designed for 30” Hg (full vacuum) and have a maximum test at 26” Hg due to facility altitude and equipment limitations.
- Maximum operating temperature of 250 deg F for EPDM, Butyl, Hypalon, and Viton; 225 deg F for Neoprene; 210 deg F for Nitrile; 180 deg F for Pure Gum Rubber; 300 deg F for EPDM and Butyl in air service at 25 PSI maximum; higher pressure and temperature ratings available.
- All sizes can be supplied with a filled arch reducing their movements by 50% and increasing the spring rates fourfold.
- For full product specifications and installation instructions, see SPEC 1104-1 and ININ 1104-1. Gross weights include retaining rings.
- WARNING: Control units (sold separately) must be used when piping is not properly anchored. Number of rods are dependent upon maximum field test pressures. Expansion joints may operate in pipelines carrying fluids at elevated temperatures and pressures, so precaution should be taken to ensure proper installation and regular inspection. Care is required to protect personnel in the event of leakage or splash. Adequate floor drains are always recommended.
- Movements are non-concurrent. Contact General Rubber for concurrent movements, and for sizes not shown up to 144” I.D.
- Series 1100 and 1200 replace styles 1025, 1050 and 1075.
